Night vision true color image acquisition method based on filtering of image intensifier

Abstract

The invention discloses a night vision true color image acquisition method based on filtering of an image intensifier, which is mainly applied to a low-light level night vision device made by an image intensifier. A technical means of coating a layer of color filtering thin film on a photon plane of a photoelectric cathode of the image intensifier is adopted, a certain interpolation algorithm is combined, and color image acquisition in a night vision condition can be realized. compared with the prior art, the method of the invention can acquire a color image with higher resolution and better image quality in the night vision condition.

Description

technical field [0001] The invention belongs to the technical field of night vision imaging, in particular to color imaging technology under night vision conditions, in particular to a night vision true color image acquisition method based on image intensifier filtering. Background technique [0002] Usually a complete low-light night vision system includes an optical imaging lens group, a low-light image intensifier, and a post-processing system. Among them, the low-light image intensifier is a vacuum device, which is the most important core device in the low-light night vision system, and can convert the received weak image into an image suitable for human eyes. [0003] So far, there have been one generation of low-light image intensifiers, two generations of low-light image intensifiers, three generations of low-light image intensifiers and four generations of low-light image intensifiers. Different generations of low-light image intensifiers have different structures, ...
